企业异质性与贸易中介理论研究新进展

Research Progress in Firm Heterogeneity and Trade Intermediation Theory

新新贸易理论诞生近十年来,贸易理论家围绕企业异质性假定进行了细致而富有成效的拓展研究。其中引人注目的是融入贸易中介的分析,打破了已有研究关于直接出口的局限,并分别基于异质性和企业内生边界视角,解释了中介技术和不完全合约对企业直接出口和中介出口等不同出口决策及福利分配的影响。本文梳理了国外最新文献中企业异质性与贸易中介理论的研究进展,解析了将贸易中介引入新新贸易理论的微观机理,并展望了其未来的发展方向。

It has been over a decade since the new-new trade theory was born,the trade theorists expanded the more detailed and fruitful research on the hypothesis of firm heterogeneity.It was remarkable that the theoretical literature trade intermediaries were integrated into the analysis,which broke the limitations of direct export in existed research and which explained the influence of intermediary technology and incomplete contracts on the different export decisions and welfare distribution between direct export and intermediary export based on the firm heterogeneity and endogenous boundary respectively.This paper reviews the recent theoretical literature on heterogeneity and trade intermediary theory,illustrates the microscopic mechanism of the integration of trade intermediation into new-new trade theory and prospects its future development direction.
